Pleistocene speciation in the genus Populus (salicaceae).

Systematic biology - 1 May 2012

Levsen Nicholas D, Tiffin Peter, Olson Matthew S

Abstract excerpt

The macroevolutionary consequences of recent climate change remain controversial, and there is little paleobotanical or morphological evidence that Pleistocene (1.8-0.12 Ma) glacial cycles acted as drivers of speciation, especially among lineages with long generation times, such as trees. We combined genetic and ecogeographic data from 2 closely related North American tree species, Populus balsamifera and P....
